CHANDELIER.

SPECIFICATION forming part of Letters raient No. 258,105, dated'May 1e,1882.

Application filed December-27, 1881. (No model.) I

To all whom 'it may concern:

Be it knownl that I, STEPHEN S. NEWTON, a

4 citizen of the United States of America, resid1 ing at Binghamton, inthe county of Broome and State of New York, have invented certain newand useful Improvements in Chandeliers; and I do hereby declare thefollowing` to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form apartof this specification.

Heretofore it has been customary in constructing chandeliers to employ astationary tube and a sliding tube, one carryinga spring mechanism andthe other having attached to it the end of a spring or the end of a cordrun`- ning to the spring. In practice it is :found that the springsordinarily used are not of sufficient power to attain the desired resultif heavy chandeliers are thus constructed. Y

My invention relates to a new construction of chandelier which has, rst,two or more sections of tubingarran ged telescopically 5 secondly, astopping mechanism concealed within the tubes, adapted to lock thechandelier in any position vertically; thirdly, a cord-winding mechanismconcealed Within an upper bulb attached to the upper stationarytube-section, the end of its cord being attached to the lower slidingtube-section; fourthly, a cord-winding mechanism concealed within alower bulb carried by the lower sliding tube-section, with p the end otits cord attached to the upper stationary section; and, fthly, to a stopmechanism constructed and arranged to permit the free passage through itof the last said cord.

Figure l is a vertical section of a chandelier embodying myimprovements. Fig. 2 is a transverse section on the line m x, Fig. 1.Figs. 3, 4, 5, and 6 are vertical sections of slightlymodified forms.Fig. 7 is a cross-.section of the device shown in Fig. 6 on line x ab.Fig. 8 is a similar section of a modied form of the same devices, thelocking-bars in this ligure being shown as made semi-cylindrical. Fig. 9is a sectional perspective-view of the lower end of the outer tube shownin Fig. 5. Referring to Fig. 1, A is the upper tube-section, providedwith the bulb or inclosing-shell B at its upper end and a swiveling hookor loop, b.

i Gis a frame supported in shell B, and having mounted thereon aspring-drum, G', to which is attached a cord or chain, o.

` D is a shaft carrying a guiding-roller, d.

E is a rack formed or attached to the inner wall of the tube A. E is thelower sliding tube-section, carrying bulb EZ at its lower end. It has ashaft, F, with a spring-drum, F', mounted thereon.

f is a cord or chain, attached at one end to the drum F and at the otherto the upper sta tionary tube-section, A, as at f.

AA guiding roller or pulley maybe mounted in the bulb E2 and adapted toproperly guide the cordfinto the tube E',`and so situated as to guidesaid cord properly relatively to the stopping mechanism to be described.

The oord o, running from the upper stationary drum, C', is secured tothe lower tube-section, E', by means of ears e or a cross-bar. Attheupper end of the lower sliding tube-section, E', there is mounted astop -wheel, H, preferably constructed as shown, with teeth or cogsadapted to engage with the stationary rack E. If the wheel H be at anypoint prevented from rotating, it will be seen that the said wheel andrack will operateas a stop or lock for` the sliding part ot' thechandelier. I have shown one form of mechanism for thus preventing therotation of the wheel H. This mechanism consists of a rod, I, carrying adetent, t', at the upper end, a spring, J, for thrusting said detentinto engagement with wheel H, pivoted levers K K for drawing rod I down,a yoke, L, and a thumb-piece, L', for pushing upward the outer ends ot'levers K K. These levers K K are at points between their ends pivoted tothe bulb or shell, as shown at k 7c in the drawings, so that'the innerendscau be thrust up or down by means of the yoke L, the arms of whichare respectively pivoted to the outer ends of these levers K K. At theirinner ends the levers are provided with slots, through which passes apin carried by the bar I. When the inner ends of the levers K K areforced down the bar I is drawn down also, the slots permitting thelevers to swing down to a sufficient extent. The spring J may be are25am?,

ranged to bear against the cross-bar J in the bulb E2, and against thepin or cross-piece j, attached to the bar I. By thrusting upward againstthe thumb-piece L' the detent z' will be drawn out of engagement withwheel H, and the lower part of the chandelier can be then moved up ordown to any desired point. When in the desired position the hand iswithdrawn from the thumb-piece L', the detent z' is thrust intoengagement with wheel H, and the chandelier is locked. Instead of thismechanism, a cord or chain and a pivoted dog could be employed to lockand unlock the wheel H.

In order to prevent the rotation of either of the tube-sections A E'relatively to each other, the one or the-other may be slotted and theother be provided withV a pin or screw. I prefer, however, to make thesliding tube polygonal in cross-section and attach to the 'bottom of thestationary tubefa cap, e', having a polygonal aperture for the slidingtube.

In the construction shown in Figs. l and 2 the aperture and the slidingtube are made square. The cord j' is arranged to pass up through thestopping mechanism to its point of attachment atf'. In Fig. 3substantially the same construction is shown, except thata modifiedlocking mechanism is employed. This locking mechanism consists of ahollow tapering portion, M, formed upon the upper end of the slidingtube-section E', and a correspondingly-shaped opposite portion, M',connected with the upper drum by the cord c. The rod or link I ispivoted tothe part M' of the stop. At the lower end it is pivoted to thethumb piece orlever L', which in this case is situated substantiallyhorizontally', being pivoted at l within the shell and provided withacatchpiece, Z', projecting through the shell. VThe cord F passes upwardthrough an aperture formed in the hollow part M of the stop to its pointof attachment at f'. By pulling down on the thumb-lever L and pushing upslightly on the chandelier the tapering or wedge-shaped locking-piecesare disengaged, and the chandelier can be moved up or down to anydesired point. In this case the locking is ei'ected by crowding the partM' outward against the stationary tube. In this case, as in theconstruction shown in Fig. l, the lock is situated at the upper end ofthe sliding tube.

In Fig. 4 a construction is shown having a supplemental tube, O,situated in the upper tube-section, A. It is provided with twodiametrically-opposite series ot' perforations, o, to receive thestop-piece.y This stop-piece P is pivoted across the upper end ot' thesliding tube, and isa little longer than the inner diameter of saidtube. The upper cord, o, is attached to the stop-piece I? by an eye, 1J.The thumb-lever Il' is connected to the stop-piece P by a cord or link,I, attached to the stop. The cord f passes by or through the stopmechanism to its point of fastening'atf'. When it is desired to unlockthe chandelier it is thrust upward a little until the stop-piece Pstrikes against the shoulders p', and then by a downward pull on thethumb-lever L' said stoppiece is drawn into the position shown in dottedlines, such position preventing it from any longer engaging with therecesses in the tube O. When thus disen ga-ged the chandelier can bemoved into any desired position and again locked by releasing thethumb-piece L', for the stop-piece I) will instantly seat itself in thenearest aperture o in tube O.

In Fig. 5 is shown a construction substantially similar to that in Fig.4, the difference being that the stop-piece I is thrust upward by meansof the thumb-piece I, such upward thrusting resulting in a disengagementof the stop-piece with the apertures o, as shown in dotted lines. Thespring I2 operates to thrust the link I down when the hand lof theoperator is disengaged.

In Fig. 6 there is shown another method of lookin g the parts of thechandelier together by means of friction, and ot' permitting the cordsof the winding mechanisms to pass properly ythrough theloekinglnechanism. In this case two locking parts, M', are used insteadof one, as shown in Fig. 3. They are constructed with opposing wedgingfaces, which opera-te to crowd them against a friction-collar or annulusat M2 in the stationary tube. vThe cord f from the lower windingmechanism passes through one of the locking-bars M', or through a slotformed therein. To prevent the locking-bars M' from rotating, they maybe made square and passed through a square aperture in the part M2, asshown in Fig. 7; or it' one of the bars be rigidly secured to thesliding section or the bulb, as shown at M3, the sliding section will beprevented from rotating relatively to the stationary section; or aset-screw may be employed, as shown at M4 in Fig. 3, this figure showingalso a portion of the slot M5, in which the set-screw moves. Thelocking-bars M' shown in Fig. 3 are more or less flexible, and.therefore the one which is secured to the bulb, as shown at M3, is notprevented from swinging outward sufficiently to come in contact with thebearing-piece. v

I am aware that chandeliers have heretofore been constructed with astationary tube and a sliding tube, and devices to prevent the rotationof one tube relatively to the other, and therefore I do not claim suchdevices, broadly.

What I claim is- 1. In achandelier,theeombination, substantially ashereinbefore set forth, of the following elements, namely: the upperstationary tube-section, a lower sliding tube-section carrying thebulbE2,a springcord-winding mechanism mounted in the upper tube-section andcarrying a cord attached to the sliding tubesection, a spring cordwinding mechanism mounted in the sliding part of the chandelier, havinga cord attached to the stationary' tubesection, and alocking mechanismcarried by the sliding tube-section at its upper end and con- IOO IIO
